[0043] Bony expanders are key orthodontic appliances used to expand the maxilla in orthodontic treatment. They apply mechanical force through components such as spiral rods, anchorage screws, and fixation bands to achieve lateral expansion of the jawbone.

[0044] Currently, skeletal expanders have the following problems: First, a cleaning blind spot is formed around the spiral bar and anchorage screw, making it difficult for traditional water flossers to penetrate the complex structure, leading to plaque accumulation and an increased risk of peri-implantitis; Second, the fixed-shape rinsing head cannot adapt to the three-dimensional anatomical shape of the expander (such as the depth of the palatal midline and the distribution of the spiral gaps), resulting in low cleaning efficiency.

[0045] To address the aforementioned problems, this utility model proposes a special flushing head for bony expanders.

[0046] Reference Figures 1 to 2 In one embodiment, the dedicated irrigation head for the bony expander includes:

[0047] The forked front end 10 includes a first forked portion 11 and a second forked portion 12, wherein the first forked portion 11 and the second forked portion 12 are forked and form a forked region.

[0048] A mechanical cleaning component 20 is disposed inside the bifurcation area, and the mechanical cleaning component 20 is used to spray water.

[0049] A malleable component 30, the first end of which is connected to the forked front end 10, wherein the bending angle and shape of the malleable component 30 are adjustable;

[0050] A connecting component 40 is connected to the second end of the malleable component 30, and the connecting component 40 is used to connect the body of the water flosser.

[0051] In this embodiment, the front end of the rinsing head for the skeletal expander is configured as a bifurcated front end 10, which can more effectively clean all parts of the skeletal expander and better reach hard-to-reach areas, thereby improving the cleaning effect. Furthermore, the bifurcated design of the front end 10 disperses the water flow sprayed by the mechanical cleaning component 20, reducing water pressure in one direction and minimizing irritation to the gums, making it suitable for people with sensitive gums. The bifurcated front end 10 also provides multi-angle rinsing, helping users clean their mouths more comprehensively, especially in cases of misaligned teeth or orthodontic appliances. The bifurcated design also increases the contact area during rinsing, thereby improving comfort and reducing discomfort. The bifurcated front end 10 can be adjusted according to different user needs, such as for teeth cleaning or gum care, providing a more flexible user experience. The bifurcation between the first bifurcation 11 and the second bifurcation 12 can form a bifurcation area, and the specific bifurcation angle can be set according to actual conditions and user needs. The forked tip 10 can be made of soft silicone with a Shore hardness range of 10-20. Using soft silicone increases the softness and comfort of the forked tip 10 and has chemical resistance, high temperature resistance, and low temperature resistance. In addition, soft silicone is easy to clean and has good sealing and wear resistance.

[0052] The mechanical cleaning component 20 sprays water or cleaning liquid in a high-pressure jet to help clean the gaps between different parts of the skeletal expander, as well as teeth and interdental spaces. The mechanical cleaning component 20 can be composed of a nozzle, bristles, and a water pipe. The malleable component 30 can be shaped by the user, for example, using a dynamically shaped conduit. This conduit can be bent and adjusted as needed to adapt to the patient's oral structure or specific needs. The materials used for the malleable conduit are typically biocompatible and safe for use in the body, such as medical-grade silicone and polyurethane. The conduit's diameter, length, and shape can also be designed and manufactured to meet different usage requirements. The connecting component 40 can be a specially designed connector, plug, or threaded connector to connect the malleable component 30 to the main body of the water flosser, thus connecting the skeletal expander's dedicated rinsing head to the main body of the water flosser, forming a complete water flosser.

[0053] This utility model's technical solution comprises a dedicated rinsing head for a skeletal expander, consisting of a bifurcated front end 10, a mechanical cleaning component 20, a malleable component 30, and a connecting component 40. The bifurcated front end 10 is composed of a first bifurcation 11 and a second bifurcation 12, which are set at a preset bifurcation angle. The mechanical cleaning component 20 is located inside the bifurcation area of ​​the bifurcated front end 10 and can spray water to rinse various parts of the skeletal expander or teeth. The first end of the malleable component 30 is connected to the bifurcated front end 10, and the bending angle and shape of the malleable component 30 are adjustable to adapt to different oral environments. The connecting component 40 is connected to the second end of the malleable component 30 and can connect to the main body of the rinsing device. This water flosser with the skeletal expander-specific rinsing head can be used to clean patients with skeletal expanders. The bifurcated front end 10 design can solve the problem of large cleaning blind spots, and the malleable component 30 can change the shape of the skeletal expander-specific rinsing head to adapt to different structural parts of the skeletal expander.

[0054] In one embodiment, the width of the first forked portion 11 and the second forked portion 12 is in the range of 3.3-3.7 mm, and the angle at which the first forked portion 11 and the second forked portion 12 are forked is in the range of 15-35°.

[0055] In this embodiment, the width range of the first bifurcation 11 and the second bifurcation 12 is set to 3.3-3.7mm to accommodate a minimum screw rod gap of 3.0mm. The bifurcation angle range of the first bifurcation 11 and the second bifurcation 12 is set to 15-35° to match the curvature of the palatal dome. For details, please refer to... Figure 7 Furthermore, the thickness of the bifurcation tip 10 can be set to a range of 0.9–1.1 mm to reduce the risk of tissue compression. In this embodiment, the end fillet radii of the first bifurcation portion 11 and the second bifurcation portion 12 of the bifurcation tip 10 can be set to ≥0.2 mm, and the surface roughness of the bifurcation tip 10 can be ≤0.8 μm. The specific parameter ranges in this embodiment are for reference only and can be adjusted according to actual conditions and user needs.

[0056] Reference Figure 2 , Figure 3 and Figure 7 In one embodiment, the mechanical cleaning assembly 20 includes:

[0057] Multiple bristle bundles 21 are disposed on the forked front end 10. The multiple bristle bundles 21 include multiple first bristle bundles and multiple second bristle bundles. The multiple first bristle bundles are disposed on the first forked portion 11, and the multiple second bristle bundles are disposed on the second forked portion 12. The multiple first bristle bundles and the multiple second bristle bundles are arranged in a left-right staggered layout.

[0058] A water pump 22 is disposed within the forked front end 10, and the water pump 22 is used to spray water at a preset frequency and pressure.

[0059] In this embodiment, the mechanical cleaning component 20 can be composed of multiple bristle bundles 21 and a water pump 22. The diameter of the bristles 21 can range from 0.05 to 0.15 mm. The first and second bristles are arranged in a staggered pattern, and the bristle density at the forked front end 10 can be 20 bundles / cm². The bristles 21 allow for targeted cleaning of the finer areas of the bony expander, improving the cleaning effect. The water pump 22 can be composed of a nozzle, a pump, and water pipes. The water pump 22 sprays water at a preset frequency and pressure to clean teeth and crevices. The water spray frequency can range from 1900 to 2100 times / minute, and the water pressure can range from 40 to 60 PSI (Reynolds number Re = 2500 to 4000). The specific parameter ranges in this embodiment are for reference only and can be adjusted according to actual conditions and user needs. Thus, in this embodiment, the mechanical cleaning assembly 20, consisting of multiple bristles 21 and a water pump 22, can be used to clean various parts of the skeletal expander or teeth and crevices. For example, in practical applications, the bristles 21 can be used to brush away dirt from the skeletal expander or teeth while the water flow can rinse away fine particles that the bristles 21 cannot reach.

[0060] Reference Figure 5 and Figure 7 In one embodiment, a plurality of micropores 60 are respectively provided on the first branch portion 11 and the second branch portion 12 of the forked front end 10. The plurality of micropores 60 are arranged in a gradient, and the position of the micropores 60 corresponds to the water outlet of the water pump 22.

[0061] In this embodiment, multiple micropores 60 are provided on the bifurcation front end 10, allowing the water pump 22 inside the bifurcation front end 10 to spray water through the micropores 60, thereby cleaning various parts of the skeletal expander or teeth and gaps. Arranging the micropores 60 in a gradient allows control of the water spray angle, achieving better cleaning results and adapting to the oral environment. The pore diameter of the micropores 60 can range from 0.5 to 0.8 mm, the gradient angle can range from 25 to 35°, and the shear stress ≥ 50 Pa (critical biofilm peeling threshold). The specific parameter ranges in this embodiment are for reference only and can be adjusted according to actual conditions and user needs.

[0062] In one embodiment, the aperture of the micropore 60 is in the range of 0.5-0.8 mm, and the gradient angle of the plurality of micropores 60 is set in the range of 25-35°.

[0063] In this embodiment, the first and second brush bristles can be set to vibrate, with a vibration frequency range that can be synchronized with the water jet frequency of the water pump 22, ranging from 1900 to 2100 times per minute. In practical applications, there will be a certain phase difference between the vibration frequency of the first and second brush bristles and the water jet frequency, which needs to be ensured to be <5%. If the phase difference is too large, it needs to be adjusted to avoid damage to the patient's oral cavity. The amplitude range of the first and second brush bristles can be 0.4-0.6 mm. In practical applications, the vibration of the first and second brush bristles can be controlled manually or by setting a motor to control the vibration frequency. The specific parameter ranges in this embodiment are for reference only and can be adjusted according to actual conditions and user needs.

[0064] Reference Figure 5 and Figure 6 In one embodiment, the malleable component 30 includes:

[0065] A malleable conduit 31, one end of which is connected to the bifurcated front end 10, and the second end of which is connected to the connecting component 40;

[0066] A reinforcing structure 32 is disposed on the inner wall of the malleable conduit 31, and the reinforcing structure 32 is used to shape the malleable conduit 31.

[0067] In this embodiment, the malleable catheter 31 can be bent and adjusted as needed to adapt to the patient's oral structure or specific needs. The material of the malleable catheter 31 typically has good biocompatibility and can be safely used in vivo, such as medical-grade silicone or polyurethane. The catheter's diameter, length, and shape can also be designed and manufactured according to different usage requirements. The reinforcing structure 32 can be a metal wire, such as a 0.8mm diameter nickel-titanium alloy wire. The surface of the malleable catheter 31 can also have a plasma-sprayed alumina coating, with a thickness ranging from 45 to 55 μm and an adhesion ≥1.2 MPa. The nickel-titanium alloy wire has a bending life >10⁴ cycles. Using the nickel-titanium alloy wire as the reinforcing structure 32 allows for bending and shaping of the malleable catheter 31, controlling the direction of the flushing end and tip of the bony expander's flushing head, and adjusting the shape of the bony expander's flushing head according to different positions and opening degrees. The reinforcing structure can be fitted to the inner wall of the malleable catheter 31.

[0072] In this embodiment, a safety control component 50 can also be installed in the main body of the rinsing head for the bone expander. The safety control component 50 detects the water pressure of the water jet from the mechanical cleaning component 20.

The piezoresistive sensor 51 detects the water pressure of the water jet from the mechanical cleaning component 20 and outputs a pressure signal to the controller 53. In this embodiment, a Hall sensor 52 may also be provided, which is installed within the main body. The output terminal of the Hall sensor 52 is connected to the input terminal of the controller. The Hall sensor 52 can detect the vibration frequency shift of the brush bristles 21 when the brush bristles 21 are in vibration mode and output a frequency shift signal to the controller 53. The controller 53 can be preset with a safe water pressure value and a safe frequency offset value. These are then compared using a comparator. When the water pressure exceeds the safe water pressure value or the brush vibration frequency offset exceeds the safe frequency offset value, the alarm 54 is activated, emitting an alarm signal to alert the user. The alarm 54 can provide both audible and visual alarms, i.e., by flashing light or emitting sound. Furthermore, in this embodiment, the controller can also control the water jet interval or duration. The specific interval and duration can be set according to actual conditions and user needs.
